Somebody is lying. New Jersey Governor Chris Christie has maintained that he knew nothing of the lane closures on the George Washington Bridge, lane closures carried out by his closest administration officials. But testimony after testimony cast more and more doubt on Christie’s claim.

In bombshell testimony Friday, Bridget Anne Kelly said that she told New Jersey Gov. Chris Christie (R) that access lanes to the George Washington Bridge would be closed for a traffic study a month before the plan actually was carried out in September 2013.

The former deputy chief of staff testified that the governor approved the study, which prosecutors allege actually was cover-up for a revenge plot against a local Democratic mayor.

Christie has long maintained that he knew nothing about the lane closures that brought traffic in the town of Fort Lee, New Jersey to a days-long standstill until he read about them in the press in late September or early October 2013. Yet Kelly and other former Christie allies have contradicted what Christie’s said about what he knew of the lane closures and when throughout the federal trial investigating the so-called Bridgegate scheme.

Telling her version of the saga for the first time from the witness stand Friday, Kelly testified that former Port Authority official David Wildstein informed her on Aug. 12, 2013 that he was moving forward with a traffic study that he said would create major traffic problems in Fort Lee, according to WABC. Kelly testified she then informed Christie about the study, and alleged he said he was alright with it.

“He said, ‘All right.’ He didn’t really react. He said that’s fine. He said, ‘How is the relationship with Mayor Sokolich’ of Fort Lee?” Kelly testified, according to Philly.com. “And I didn’t know. I really didn’t know.”

The next day she sent the email that would cast a shadow over Christie’s administration for years to come: “Time for some traffic problems in Fort Lee,” she wrote to Wildstein.
